FM Aerial lead splitting?

[BenW]

Hi, we have a fm reciever on out aerial pole and its currently just going into the stereo through a hole in the wall.

Now the aerial is right next to my bedroom and i wan't to change the aerial socket from tv to fm.

Where can i buy an external fm splitter to stick on the outside of the house?

Thanks
Ben

you can probably just splice the wire yourself
